Scale

When working with larger models you probably will reach a point when the
model becomes too large to fit on the page. You can change the scale of
an individual Assembly on a page by right-clicking the Assembly image
and choose Change Scale from the pop-up:

Please note that some options shown here are not always available.
There can be more or less or other kind of options in this menu.

A new dialog will show in which you can change the scale:

The default Model Size 1,000000 is 100%. You can type in a new value or
use the small arrow buttons to decrease the scale. Of course you can
also increase the scale. Click OK when done.
Finally then you are given the choice of changing only the current step or not:

Obviously you should choose Yes here, since the scale of previous
assemblies can stay as they are. Choosing No will result in rescaling
all assemblies. Would this be necessary it is better to change the
Global Scale settings for scale.
